My invention relates to sheeting machines,’ its rotation.‘ The arms ll pass through and extend primary object being the provision of a'device' to both'sides of the cylindrical members I2 to . which reels sheet material from the roll and into which they are secured by means of set screws [4. a convenient form for cutting'the material‘into The‘ bars l5span the distance between the end portions vof the arms ll, these being the bars on which the sheet material is reeled. Clamps I6 sheets of the desired length.

These clamps are‘split .as shown in Figure vV3 tained by tightening the screws l1.

Another and a very important object of the in 15 vention is the provision of a knife guide ‘on the reel so that the material may be most effectivel out into sheets of the desired length. there is very little difficulty from binding but the 7 ' ‘ I also have in 'view the provisionof "a clamp" for securing ‘the material at its end edge to the 20 reel, the clamp being operative inla manner so 'that the reel may beturned in either direction to unroll the material from any one of a plu rality of rolls which are supported on the frame of the'machine. 25 tension increases rapidly with the number of layers on the reel and it is when the tension in-v creases that the loose connection of the bars I5. 20 with the clamp l6 compensates to a very large - extent for the binding action. The spacer or spreader I8 is ?rmly secured at its'opposite. extremities to the two cylindrical ' . Having in view these objects ‘and others which members. I2. This spreader functions not’ only will be pointed out in the following description, I v to‘ spread the two layers of sheets on the reel 25 will now refer to the drawing, in which but it serves also as a knife guide and as a ' Figure 1 is a view reel. 30 This loose connection is for the purpose of ‘preventing binding action especially after a number of layers of the sheet material has been reeled.’ At the beginning of the reeling operation in perspective of ‘the entire (support for the paper clamp.

The spreader may be either laminated as shown in Figures 1, 2, and 4 30 or of integral ‘construction as shown at l8"in Figure 5. A clamp 22 is hingedly secured to one 35 bars and the clamps which secure the bars tothe, of the plates I9 or 20 by means of hinges .23.‘ The 35 reel arms. 7 , p . clamp furtherincludes a screw 24 passing through Figure 4 is an enlarged perspective view of the a suitable aperture in the clamping member 22 clamp which I employ for securing the. roll ma and into either of the plates l9 or 20. terial at its free end edge to the reel, a fragment; In use the material is unrolled from‘ a roll 25 40 of the spreader bar being also shown. ‘ J Figure 5 is a view in side elevation of the reel‘ in slightly modi?ed ‘form in position on itsframey the’ frame being shown in conventional form; f ' The frame ID of the machine is shown in very conventional form in Figure 5. This frame may be varied in numerous ways, its function being. primarily to support the reel at a convenient ' height and to support one or more rolls of the 50 material which is to be reeled and cut into sheets. The reel assembly is shown in Figure 1. It includes arms II projecting radially from cylin drical members 12 which terminate in the spindles l3. These arms I I may be provided with calibra tions as shown in Figure 2 in which the numerals 55 l and 2 may indicate distances from the axis of and its free' edge is secured by means of the 40 clamp 22. The reel is then turned‘ by hand by means of the crank 26 so that the material is wound on the reel. Where only one rolb is em ployed, one clamp 22 will serve the purpose as‘ the rotationof the reel will always be in the . same direction. When a number of rolls are sup ported on the frame H], a secondroll 2? may be in position such that it will not readily reel but this difficulty may be overcome ,by the use of clamps 22 on both sides of ‘a spacer. The spacer may be the spacer I8 comprising the sev eral parts as shown in Figures 1, 2 and 4, or it may be integral as indicated at l8’ in Figure 5. My sheeting machine is designed for use pri 'marily with Cellophane. Great di?iculty is en 55 2 . 2,132,937: 5; secured to said reel and transverse to the plane thereof, said reel and said web spacing bar having in common the axis of rotation, menibers having countered in cutting this material because of its relative; hardness and because of its peculiar 7 curlin-gf qualities. A shear action is wholly un satisfactory anji the number of layers which a loose connection at the corners of said reel to can be thus cut is very limited. For this rea son I provide a novel form of cutting guidewhich prevent binding of the material during the wind ing thereof, and a gnide on said web spacing bar will function with the blade ofiran ordinary jack knife or any other suitable cutting blade. The plate 2| is narrower than the plates is and 20, 10 thus affording‘: a channel between the plates. l9 for the insertion of a cutting blade for guiding the sliding movement of a cutting bladeto out the webs of reeled material. and as for the passage of a cutting blade, this action, it is suf?ciently brittle especially when under tension to respond readily to the sliding knife action of a cutting blade sliding in the 20 groove between the plates l9 and 20 of the I8. ‘ .
